Hackers broke anew into the online home of the Linux operating system last week, prompting administrators of the Linux Foundation to temporarily take their websites offline.
The Linux Foundation said its infrastructure, including Linux.com and LinuxFoundation.org, were taken "down for maintenance" following the security breach discovered Sept. 8.

"Linux Foundation infrastructure including LinuxFoundation.org, Linux.com, and their subdomains are down for maintenance due to a security breach that was discovered on September 8, 2011. The Linux Foundation made this decision in the interest of extreme caution and security best practices. We believe this breach was connected to the intrusion on kernel.org," it said in a message on its website.

Last August 28, a security breach was discovered at the Linux Kernel Archives (www.kernel.org), although administrators said the breach may have occurred weeks before.
